[Q] TCP Send & Retrieve

Unity Engine
1

Hello,

I am writing a short script which will get a response from a server, and need some advice.

The code I have so far is as follows:

using UnityEngine;
using System.Collections;

public class tcpSession : MonoBehaviour {


    public void Request(string message, string returnMethod) {
        // Open sockets session
        StartCoroutine(socketRoutine(message, returnMethod));
    }
   

    IEnumerator socketRoutine(string packet, string returnMethod)
    {
        // Start TCP session, Send Packet, Wait Reply (or timeout), Fire returnMethod with response output. Close TCP session.
        string output = "";

----->>> SOMETHING HERE...

        // Fire returnMethod with output
        Fire(returnMethod, output);

        // Break the Coroutine...
       yield break;
    }

    void Fire(string method, string value)
    {
        SendMessage(method, value);
    }
}

It works by having another script call the Request Method, and providing a return method. The request is processed using a coroutine to keep the UI running smoothly. I would like to send the ‘packet’ / message to a TCP server, wait for reply (or timeout after 10 seconds), and then set the output which fires the message back to the returnMethod.

What’s the best way to send a TCP message, and wait for a reply?

Solved, using an example from another TCP Client/Server C# project. It works for my application, but not suitable for games as it still causes a lockup of the main threads.
